Matt Kenseth: Leads Opening Las Vegas Practice

Update: Kenseth was fastest in opening practice for the Kobalt Tools 400 at Las Vegas Motor Speedway on Thursday. He turned a fast lap of 187.396 mph.

Recommendation: NASCAR gave the teams a whopping 3-1/2 hours to shake the cars out at the Vegas oval on Thursday. Kenseth stood tall for JGR and the Toyota camp. His No. 20 Toyota edged Carl Edwards and his Ford for the fastest lap of this first practice session. Kenseth could challenge for the win in Sunday's Kobalt Tools 400.
